Ingredients You’ll Need

(Makes about 16 slices | Prep Time: 10 minutes | Chill Time: 2 hours)

  • 250g digestive biscuits or graham crackers, crushed
  • 200g mini marshmallows
  • 1 cup shredded coconut
  • 1/2 cup unsalted butter, melted
  • 1 can (14 oz) sweetened condensed milk
  • 1 teaspoon vanilla extract

Optional toppings:

  • Melted chocolate for drizzling
  • Sprinkles for decoration
  • Extra coconut for garnish

How I Make No-Bake Marshmallow Slice (Step-by-Step)

1. Prepare the Pan

I line an 8×8-inch baking dish with parchment paper, making sure there’s enough overhang to lift the slice out easily later.

2. Crush and Combine

In a large bowl, I combine the crushed biscuits, mini marshmallows, and shredded coconut.

3. Add the Wet Ingredients

I pour in the melted butter, sweetened condensed milk, and vanilla extract. I mix until everything is evenly coated and sticks together.

4. Press and Chill

I press the mixture firmly into the prepared pan, making sure it’s evenly spread out. Then, I pop it into the refrigerator for at least 2 hours to firm up.

5. Add Finishing Touches

Once chilled, I sometimes drizzle melted chocolate over the top and sprinkle extra coconut or colorful sprinkles for a festive finish.

6. Slice and Serve

I lift the slice out of the pan using the parchment overhang, cut it into squares, and serve. They’re soft, chewy, and always a hit.

My Favorite Tips for Perfect Marshmallow Slice

  • Use fresh marshmallows: They make all the difference in texture.
  • Press firmly into the pan: Helps the slice hold together when cutting.
  • Chill thoroughly: Don’t rush this step — it needs time to set.
  • Add a little crunch: Chopped nuts or crispy rice cereal can add a fun twist.
  • Cut with a sharp knife: Wipe the blade between cuts for clean edges.

What I Serve with This No-Bake Treat

This slice is sweet and rich on its own, but I love pairing it with:

  • A hot cup of coffee or tea
  • Fresh berries for a fruity contrast
  • A scoop of vanilla ice cream for extra indulgence
  • A sparkling lemonade or iced tea for summer gatherings

FAQs (From My Kitchen to Yours)

Q: Can I freeze marshmallow slice?
A: Yes! Store in an airtight container with parchment between layers for up to 2 months. Thaw in the fridge before serving.

Q: Can I use large marshmallows?
A: You can, but I recommend chopping them into small pieces for better texture and distribution.

Q: Can I make this gluten-free?
A: Absolutely! Just use gluten-free biscuits or graham crackers.

Q: How long does it last?
A: It keeps well in the fridge for up to a week — if it lasts that long!
